Abstract

The utility model relates to a waveguide window, including the framework, set up in the framework one deck or multilayer waveguide shielding layer and with framework outside fixed plate and the shield plate along fixed connection, be equipped with a plurality of mounting holes on the fixed plate, inner wall of the frame body is equipped with a plurality of mounts, a plurality of windows are cut apart into in with the framework to the mount, shield plate and framework and mount fixed connection, adopt above -mentioned structure after, can control the area of waveguide window's waveguide shielding layer through the installation quantity of shield plate to change waveguide window's shielding effect and ventilation effect, with the different demand of adaptation equipment, improved waveguide window's adaptability.

Description

Waveguide window

Technical field

This utility model relates to electromagnetic shielding field, particularly waveguide window.

Background technology

In order to closed shield body keeps the circulation of air, need on shield shell, output window, but must install Meeting the waveguide window of response criteria, the function of waveguide window stops electromagnetic signal while being to ensure that air circulation Leakage.Ventilation waveguide window is the main thoroughfare of shielding room air and extraneous exchange, and it can effectively end Passing through of electromagnetic wave, in the case of waveguide window thickness is constant, area is the biggest, and shield effectiveness is the poorest, existing Waveguide window be difficult in adapt to different shield effectiveness and the requirement of ventilation effect, and waveguide window is in use Easily entering dust, rainwater is also easily accessible, and affects equipment safety.

Summary of the invention

The waveguide window that the purpose of this utility model is to provide a kind of strong adaptability, shield effectiveness is good.

The technical scheme realizing this utility model purpose is as follows:

Waveguide window, one or more layers waveguide screen layer including framework, being arranged in framework and with framework outside Fixed plate and the barricade of connection is fixed at edge, and described fixed plate is provided with multiple installing hole, described framework Inwall is provided with multiple fixed mount, and described fixed mount will be divided into multiple window, described barricade and frame in framework Body and the fixing connection of fixed mount.

After using said structure, the waveguide screen layer of waveguide window can be controlled by the installation quantity of barricade Area, thus change shield effectiveness and the ventilation effect of waveguide window, the demand different to adapt to equipment, Improve the adaptability of waveguide window.

Preferably, in order to promote the shield effectiveness of waveguide window and play dust-proof effect, described waveguide screen layer It is provided with multilamellar, between described waveguide screen layer, is provided with drainage screen.

Preferably, in order to avoid offering wiring hole on equipment box, affect the shield effectiveness of equipment, described Framework is provided with external string holes and internal wiring hole, and described external string holes and internal wiring hole lay respectively at fixed plate Both sides.

Preferably, in order to realize the rainproof effect of waveguide screen layer, described waveguide screen layer is multiple cut-off wave Leading the waveguide bundle of composition, the axis of described cut-off waveguide is arranged the most obliquely.

Preferably, in order to promote the aisle spare of cut-off waveguide, the cross section of described cut-off waveguide is hexagon.

Preferably, waveguide bundle assembling for convenience, described waveguide bundle is welded by the sheet metal of multiple bendings and is formed, Each sheet metal is provided with multiple bending side, and adjacent bend face angle is 120 °, and alternate bending side angle is 60°。

Preferably, in order to promote shield effectiveness, described barricade is provided with electromagnetism towards the one side of waveguide screen layer Sealing gasket.
